Method for planting phoebe bournei in forest gaps in hilly and mountainous regions

Abstract

The invention discloses a method for planting phoebe bournei in forest gaps in hill and mountain regions, and belongs to the technical field of afforestation. Phoebe bournei afforestation is carried out by manually forming gaps, and the manually formed gaps involve manually formed plaque-shaped gaps or manually formed strip-shaped gaps. a The method has the advantages that the method overcomes the influence of strong light in the early stage of phoebe bournei slash afforestation and weak light in the later stage of the afforestation under the canopy on the growth of the phoebe bournei, the formed gap environment can provide certain shading conditions for the growth of nursery stocks in the young stage, sufficient light needed in the later stage of nursery stock growth can be met, the healthy, good and rapid growth of the phoebe bournei can be effectively promoted, by means of the method, the group advantage and the edge advantage of phoebe bournei growth can be brought into play, the formed microclimate can effectively relieve damage of severe weather to the phoebe bournei growth, according to the method, the forest land space can be fully utilized, comprehensive forest tree cleaning and land preparation are limited, water and soil are kept, and the ecological environment is favorably protected.

Description

technical field [0001] The invention relates to the technical field of afforestation, in particular to a method for planting Nannan in forest gaps in hilly and mountainous areas. Background technique [0002] Fujian Nan [Phoebe bournei (Hemsl.) Yang], commonly known as Phoebe, is a unique species in my country. It belongs to the evergreen broad-leaved tree of Lauraceae (Lauraceae) Phoebe (Phoebe). wild plants. Fujian Nan is famous for its precious materials. It is dense and tough, not easy to warp, crack, easy to process, smooth beveled surface, beautiful texture, fragrant and durable, and durable. It is a high-quality building and furniture material. [0003] Due to the huge economic value of Nannan, its wild resources have been severely damaged for a long time and are now almost exhausted. It has become a top priority to vigorously develop plantation forests to solve the shortage of resources in southern Fujian and meet people's demand for precious timber. [0004] In re...

AI Technical Summary

Problems solved by technology

[0004] In recent years, various places have actively carried out research on plantation technology of Nannan fujian in hilly and mountainous areas. However, both under-canopy afforestation and land-removed afforestation techniques, which are mainly promoted and applied in production practice, have certain advantages and disadvantages: the former has a higher survival rate of afforestation, and the first 4 years It grows fast and well, but as the canopy density of the upper canopy increases, the ground diameter grows slowly, the height-to-diameter ratio increases, the trunk is slender, the branches and leaves are sparse, and it has the characteristics of the understory trees of the canopy. If the upper trees are cut down, the production operation will encounter difficulties , the contradiction between harvesting and protection is difficult to solve; the latter is cultivated in bare land, because of the strong light, the growth advantage of tree height in the early stage is not obvious, the stand canopy is closed and the growth of forest is slow, the period of fertilization and tending is prolonged, and the management cost is high. In the case of harsh climate and natural environment, it will also be affected by drought and frost, and take the risk of afforestation failure
